Abstract

Penelitian ini bertujuan untuk mengetahui ameliorasi berbagai tanah marginal untuk peningkatan produksi tanaman okra (Abelmoschus esculentus L. Moench). Penelitian ini dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Asahan, Kabupaten Asahan, Provinsi Sumatera Utara, dengan topografi datar ketinggian tempat 24 mdpl. Penelitian ini dilaksanakan pada bulan Desember 2020 sampai Maret 2021. Bahan yang digunakan dalam penelitian ini adalah benih okra hijau, pupuk kandang kambing, arang sekam padi, dolomit, tanah top soil, tanah bakau, tanah bekas kerukan, tanah gambut. Bahan yang digunakan dalam penelitian ini adalah cangkul, garu, polybag, gembor, meteran, sprayer, pH meter, kalkulator, timbangan, papan plot dan alat tulis. Penelitian ini disusun berdasarkan Rancangan Acak Kelompok (RAK) Faktorial yang terdiri dari 2 faktor perlakuan dan 3 ulangan. Faktor Pertama adalah Tanah Marginal yang terdiri dari 4 taraf yaitu M0 = Tanah topsoil M1= Tanah bekas kerukan M2 = Tanah bakau M3 = Tanah gambut. Faktor kedua adalah Ameliorasi yang terdiri dari 3 taraf yaitu A1 = Pupuk kandang kambing   1.125 g/tanaman A2 = Arang sekam padi 1000 g/tanaman A3 = dolomit 60 g/tanaman. Hasil penelitian ini menunjukkan bahwa Tanah marginal tidak memberikan pengaruh nyata terhadap parameter amatan yang ada.

Abstract

Tomatoes are essential for Indonesians because they have high economic and nutritional value. In addition, as population growth increases, the demand for tomatoes also increases. Based on this, it is essential to research to predict the future development of tomato crop production. The research in this paper uses a dataset of tomato plant production in Indonesia, which is spread across 34 provinces in the last seven years, namely from 2015 to 2021), which is sourced from the Indonesian Central Bureau of Statistics and the District/City Agriculture Service of each Province. The algorithm proposed in this study is the Fletcher-Reeves Conjugate Gradient Algorithm which will be processed with the help of Matlab2011b. Research analysis with three network architectural models: 5-7-1, 5-13-1, and 5-17-1. Based on a network comparison of the three architectural models, the best result is the 5-17-1 model because the MSE value is the smallest compared to the other two models, namely 0.0009915 compared to 0.0010851 and 0.0049764, as well as the highest level of accuracy, namely by 94% versus 91% and 88%. Therefore the 5-17-1 model is used to predict the yield of tomato production in Indonesia for the future (2022 and 2023). Based on the prediction results at the end of 2022 and 2023, there are 18 provinces where tomato crop production has the potential to increase, although not too significantly. The prediction of tomato production using the Fletcher-Reeves algorithm is quite good because it produces a small error rate and high accuracy.

Abstract

Community service is an activity that realizes and improves the quality of community knowledge in helping the problems experienced by the community in the community. Through the Thematic Real Work Lecture (KKNT) program based on community service, this activity is to increase students' sense of solidarity with the existing conditions of the community. The use of land with hydroponic cultivation is an alternative that can be done by utilizing minimal yard land and being able to use used goods. Farming with hydroponics is very environmentally friendly in addition to not using pesticides, also the production can be used alone or as an economic source of household income. In addition, the outputs obtainedare n: (1) Improvement of superior quality of resources; (2) improving household economic resources; (3) Encourage the progress of the village. On the other hand, to ensure the discipline and participation of KKNT student participants and the community, by seeing the success in the form of outputs produced

Abstract

Palm oil production has an essential role in the regional and national economy. Accurate and reliable predictions are fundamental in planning and decision-making in the oil palm plantation sector. This study aims to predict the production of oil palm plantations on the island of Sumatra in 2023 using the Bayesian Regulation algorithm. This method was chosen because it combines historical data and new information and considers the risk factors that affect palm oil production. Historical data on palm oil production on the island of Sumatra were obtained from the Central Bureau of Statistics and analyzed using the Bayesian Regulation algorithm. The oil palm production prediction model is evaluated using accuracy and prediction error metrics. The research results are expected to provide reliable and accurate predictions for palm oil production on the island of Sumatra in 2023. This research produces a reasonably high accuracy rate of 90% (10% margin of error) and a trim MSE level of 0.00388775674 with a target error of 0.009. The research results predict that palm oil production on the island of Sumatra will decrease compared to previous years (2018-2022). This prediction provides more precise insights to stakeholders such as farmers, producers, government, and industry players in production planning, resource management, budget allocation, and effective decision-making. This research also has the potential to contribute to the development of science, especially the development of more sophisticated and efficient prediction methods, both for palm oil production and other plantation sectors, using the Bayesian Regulation method.
